Phlebia

Phlebia is a genus of fungi belonging to the family Meruliaceae. These fungi are typically found growing on decaying wood in forest ecosystems. The fruiting bodies of Phlebia species, often referred to as basidiocarps, are generally resupinate, meaning they grow flat against the substrate. They can vary in texture and appearance, sometimes being thin and membranous, while other species may have more substantial, hydnoid or odontioid structures with teeth or spines.

The hymenium, the spore-bearing surface, is usually smooth, wrinkled, or toothed. Coloration can range from white, cream, or yellow to orange or reddish hues, often depending on the species and the specific substrate. Phlebia species are saprotrophic, playing a role in the decomposition of lignin and cellulose, thus contributing to nutrient cycling in their environment. Identification of specific Phlebia species often relies on microscopic features, such as the shape and size of basidiospores and the presence of clamp connections in the hyphal system. While some species may be widespread, others are more restricted in their geographical distribution. Their ecological significance lies primarily in their role as wood decomposers.
